What is the heterotrophic hypothesis on the origin of life?
As per to the heterotrophic hypothesis the first living beings were very simple heterotrophic organisms that is not producers of their own food, which emerged from the gradual association of organic molecules into small organized structures (the coacervates). The first organic molecules within their turn would have appeared from substances of the earth's primitive atmosphere submitted to strong electrical discharges, to solar radiation and to high temperatures.
